To all whom t may concern.'

Be it known that I, Ricanoo DocAMro, a subject of the King of Spain, a merchant, residing at Calle Maipu 671, Buenos Aires, Argentina, have invented an Improvement in a Mouthpiece for Smoking Tobacco, ot which the following description, in connection `vith the accompanying drawings, is a specification, like characters on the drawings representing like parts.

rlhis invention relates to a novel system of mouthpiece for smoking cut or relatively finely divided tobacco, such as used in .pipes or cigarettes, for example an essential feature of which consists in the particular arrangeA ment of the tobacco and in the provision ot means for gradually pushing or conveying the same to the place of its combustion. Owing to this arrangement, no smoke will be allowed to pass through the column of tobacco, thereby drying and saturating the saine with nicotine, as is the case in connection with common mouth-pieces and tobacco pipes. In consequence, the strength and aromatic qualities of the tobacco will not be impaired at any time while theL chargel is being consumed. Preferably also the smoke will be conducted from. the burning tobacco to the mouth piece through a separate passage.

Vith a mouth-piece according to my invention, only tobacco is smoked, that is, without the strip of paper which actually envelopes the cigarettes and which so much prejudices the health of smokers.

To the above important advantages and those inherent to theI uniform combustion and the preservation of the strength and aromatic qualities or" the charge, is to be added the saving realized by the fact that this device allows of consuming the entire charge of tobacco introduced thereinto.

My said mouth-piece substantially consists ot a cylindrical body, provided with an elongated duct or opening intowhich the tobacco is filled and within which moves a small disc, operated by a spring which gradually pushes the tobacco towards the point ot. its combustion as this latter is progressing.

' ings have been annexed to `this specification,

in which Y Figure l shows a. mouth-piece or tube constructed in accordance with theinvention, being partially charged with tobacco. Figure 2 represents a central longitudinal section of the same, and f Figure 3 is a section along the line A-B of Figure l. j A 1 y n said drawings, `1 indicatesthe tubular body at the end or' which is formed a small enlargement 2 which forms the space of combustion and at the bottom rof whichhas been provided an orifice which corresponds'with.

the suction tube 3, Whose opposite orifice is situated at the centre of the end which constitutes the mouth-piece proper and whichffo'r that purpose has been suitably recessed and shaped Vfor its better adaption. Said body 1 is providedwith an elongated openingl or duct Within which., moves a pusher herein a small diso, secured Vto the ring 5 andoperated by a spring 6. F or the purpose of facilitating the operation of filling, a slot 7 has beenformed at the end of saidelongated'duct which allows of retainingthe disk whilelling in thetob-acco, said 'retentio-n being, obtained by slightly turningthe ring 5 so as to cause the disc to engage with the slot.

The operation is as follows The pusher disk may be retained in its position of maximum retraction, to facili-Y tate loading the device, by turning the saidr ring 5 into engagement with the retaining slot 7. Then, the tobacco is introduced, either cut in form of threads or relativel finely divided particles, so as to fill all the space between the elongated opening and the enlarged end, or place oi combustion. Thereupon, the pusher disc is releasedand the tobacco is lit, at a point corresponding to the enlarged end of the mouth-piece. In this way, the suction exerted through thc tube or passage 3, acts upon the tobacco 'charge at the forward end of the smoking tube or mouth-piece, andv will maintain combustion at said enlarged end and the tobacco 100 will be conveyed or pushed towards said point as its consumption progresses, owing to the action ot the pusher plate 4 which, as before stated, is operated by the spring 6.

By this means, the column of tobacco is gradually pushed towards the place of combustion without being heated or traversed by the smoke, such as is the case with the ordinary mouth-pieces, since the smoke passes by the tube 3 from the point of combustion directly and only to the smokers mouth. It will also be noted that the smoke does not pass through the disk Il, nor through the chamber containing the spring 6, thus avoiding the deposit upon said spring or disk, or within said chamber, ot' anyproducts of combustion due to cooling or otherwise, which might impair the proper functioning of said disk or spring and would necessitate cleaning or' said parts in order to secure their proper operation and to keep the smoking tube sweet.

It will be understood that the 'form of construction of the mouth-piece shown in the drawings, merely is to be considered by way or example, as without changing the system, the mouth-piece may be provided with several dismountable parts, for allowing of the same to be readily cleaned, and also its form or outer design may be modified in many Ways.

Having now particularly described and ascertained the nature oi' my said invention and in what manner the same is to be performed, I declare that what I claim is l. A device of the class described comprising in combina-tion, a mouthpiece, a reservoir closed at both ends and having a supply opening extending substantially the length thereof for replenishing the supply of tobacco, a portion of said reservoir constituting a combustion area, means for progressively moving the tobacco in said reservoir toward and into said combustion area,

and a passage providing communication only between said combustion area and said mouth piece for conducting smoke to the mouth piece without contacting with the reserve supply of tobacco in said reservoir.

Q. ln a device of the class described, in combination, an elongated reservoir to receive a supply of tobacco and including a combustion area. adjacent one of its ends, a pusher arranged for movement in said reservoir toward said combustion area, spring means tending to move said pusher toward said combustion area, means including a slot adapted to permit the turning oi' said pusher to epect the retention thereof in its retracted position during the filling of the reservoir, and a suction passage providing communication directly and only between said mouthpiece and said combustion area.

3. In a device of the class described, in combination, a tubular tobacco container closed at both ends and having a lateral opening for replenishing the supply of tobacco, a mouth piece at one end of said tubular container, a passage communicating with said mouth-piece and the opposite end of Vsaid tubular container, means including a disk arranged within Isaid tubular container for progressively moving the tobacco therein against the end of said container with which said passage communicates, and a ring connected with said disk through said lateral opening, adapted partially to surround said reservoir and constitute positioning and guiding means for said disk.

ln testimony whereof, I have signed my name to this specication.
